Proposed Provision: After the normal retirement age (NRA) reaches 67 for those age 62 in 2022, index the NRA to maintain a constant ratio of expected retirement years (life expectancy at NRA) to potential work years (NRA minus 20). We assume the NRA will increase 1 month every 2 years. Also, raise the earliest eligibility age (EEA) for retired-workers, aged widow(er)s, and disabled widow(er)s by the same amount as the NRA starting for those attaining EEA in 2017.
